20-Deoxynarasin sodium salt (200 mg) was dissolved in ethyl acetate (10 ml). This solution was washed with 0.1 N HCl (10 ml) and then twice with water (5 ml). The resulting organic layer was evaporated to dryness to give a residue which was redissolved in dioxane and lyophilized to give 139.6 mg of 20-deoxynarasin free acid as a white solid.
